WILLIAM N. STRING-ER, OF SOUTH BEND, INDIANA, ASSIGNOR, TO OLIVER CI-IILLED PLOW WORKS, OF SOUTH BEN'D, INDIANA.

GANG-PLOW.

Plows; and I do hereby declare the follow- I 'ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertalns to make and use the same.

This invention relates to improvements in vwheels 11-11 located near and behind respective ends of the frame, and a caster wheel12 located at the free end of the front beam 3. The mountings and means for ad engine gang plows and more particularly to the truck frame,one object of my present invention being to provide simple and efiicient means for adjusting thewheels of said truck frame to level the latter.

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the I claims.

' In the accompanying drawings, Figure ,1 is a plan view of a truck frame embodying my improvements; Fig. 2 is a side elevation; Fig. 3 is an enlarged sectional view on the line 3-3 of Fig. 2; Fig. 4 is an enlarged sectional view on the line 44 of Fig. 1; Fig. 5 is an enlarged'sectional view on the line 55 of Fig. 1, and Figs. 6, 7, 8 and 9 are enlarged detail views.

1 represents a truck frame, comprising a rear diagonal angle beam 2; a front or draft angle beam 3, disposed at right angles to the line of draft and secured at one end to the beam 2, and an angle beam 4 disposed.

parallel with the line of draft and secured at its respective ends to the rear diagonal beam 2 and the front draft beam 3. The truck frame also comprises in its structure, a brace beam 5, disposed throughout the greater portion ofits length parallel with the diagonal beam. One end of the bra'ce beam 5 is secured to the front or draft beam 3 and is bent at a point a comparatively short distance from its other end and secured to the rear beam 2. The brace beam 5 passes under the beam 4 and is rigidly secured to.

the latter and a brace 6 is secured at one end to the beam 5 where the latter is bent, and the other end of this brace is secured to the rear beam 2. The front or draft beam 3 projects laterally beyond its connection with the beam 4, and to this projecting end of the latter,'one end of an angle beam brace 7 is secured, preferably through the medium Specification of Letters Patent. Patented July 14,1914,

Application filed September 17, 1913. Serial No. 790,343. I I v ofa tie plate 8. The brace 7 is disposed at right angles to the rear beam 2 and is secured at one end thereto, the intermediate portions of said brace beam 7 being secured to the beams 4 and5,

A plurality of brackets 9 project from the diagonal rear beam 2 for the reception of connecting means (not shown) for a plurality of plow beams shown diagrammati cally at 10.

The truck frame is supported on rear justing the trailing wheels l111 are the same for both of said wheels, and a detail description of one set of these devices will I suffice for both.

The axle of each trailing wheel 11 is disposed between the rear end portions of two bars 13 13, the forward ends of which are secured to the respective sides of and separated by a spacer 14having a forwardly projecting arm 15. Pivot blocks 16are secured to the respective bars 13at opposite sides of the spacer 14 and these blocks are pivotally supported near the lower ends of plates 17 secured to and depending from the side members of one of the brackets 9. The bars 13 and spacer 14 constitute a lever pivotally supported below the truck frame by the plates 17 secured to the truck bracket, the trailing wheel 11 being connected with'one' end of such lever, and arm 15 of the spacer (which constitutes a portion of the forward arm of thelever) being of sufiicient length to project under the rear diagonal bar of the truck frame. The forangle beam. 2 and is mounted in a bearing 1 bracket 22 secured to the vertical flange of said angle beam. The bracket 22 is made with an upward projection or hub 23, upon which the hub of a hand wheel 24 on the threaded upper end of the rod has a bearing. ltis apparent that by operating the hand wheel, the rod 20 will be raised orlowered (according to the direction in which the hand wheel may be turned) and the lever formed by the parts .1l13 14 15, will be turned on its bearings afforded by the depending plates '17, and thus the rear portion of the truck frame may be raised or'lowered at one or both ends for leveling the same. 7

The caster wheel 12 is mounted at the rear ends of two bars 25, the forward ends of i said bars being secured to respective sides of a'bracket 32 secured to the free end of the front or draft beam 3 of the truck frame. A post 33 is located upon the-bracket 32' and through this post a rod 34 -passes,the upper end ofcsaid rod having a hand wheel "35 securedthereto. The rod 35 also passes through the tubular pivot post 31, and its lower portion is threaded and enters an elongated opening 36 in the spreader 26. A nut 37 is mounted in the opening 36 of the spreader, 2 6 for the reception of the threaded portion of the rod 34, and said nut is prevented from turning by engagement with the'parallel walls of said opening, 36. A

collar 36 on the rod 34 engages the bottom ofthe bracket 31.

From the construction and arrangement as above described, it will be seen that the caster wheel 12 may swing horizontally by reason of the pivotal connection, of the bracket 29 with the bracket 32 and that by turning the v, of the truck frame for leveling the same.

Various slight changes mlght be made in rod 34, motion will be imparted, through the medium of the nut 37, to the pivoted spreader 26 for raising 0r lowering the same and said. caster wheel; The spreader 26, bars 25 and caster wheel, thus constitute a lever, the operation of which will eifect the raising .or' lowering of the forward portion the details of construction of my invention without departing from'the spirit thereof or.

limiting its'scope and hence 'Idonotwish to restrictmyself to the precise details herein set forth. I V v r I Having fully described my invention what I I claim as new and desire to secure by Letters-Patent, is v 1. In a gang plow structure, tl'lQCOIIlbll'lfltion with a truck frame, andbrackets there on, of: pairs ofbars,",a wheel "mounted be-- tween the rear ends of the bars of each pair,

a spacer between the forward ends of the barsof each pairand projecting forwardly therefrom, means pivotally connecting said bars and spacers Withsaid brackets,"a vertical rodconnected'with each spacer, bearings for said rods, and a hand wheel on each of said rods.

2. In a gang plow structure, the-combinaition with a truck frame, and a bracket there.- on, of a spacer pivoted at one end to said bracket, said spacer provided with an opening having flatfwalls, bars secured to said a vertical rod mounted onthe truck-frame and having a threadedv portion passing through said spacer, a nut on said rod 111 the opening in the spacer, and a hand-operated device on said rod for turning the -latter. 0

3. Ina gang plow structure, the combination with a truck frame, of a fixed bracket secured to the truck frame, a bracket mountspacer, a wheel mounted between said bars,

ed on the fixed bracket to swing horizon-:

tally, wheel bars,-a spreader between said wheel bars and pivotally connected with said swinging bracket, a wheel mounted between the rear ends of said wheel bars,-a nutcara threaded portion passing through saidnut, and means for turning said rod.

'ried by said spreader, arod passing through the brackets on the truck. frame and having vIn testimony whereof I have signed tliis.
